In a resolver, a detecting stator core includes a first detection winding group, a second detection winding group, and a plurality of excitation windings. The first detection winding group includes a plurality of first windings as detection windings. The second detection winding group includes, as detection windings, a plurality of second windings different from the first windings in the phase of the detection voltage. The excitation windings are each wound around one of teeth of the detecting stator core. Each first winding and each second winding are wound around different teeth from each other without being wound around the same tooth. The detection winding and the excitation winding that are wound around the same tooth are arranged so as to be separated from each other in a radial direction.
